Logitech Wireless Headset with Jessie

One of those irritations.

Logitech H800 wireless headset, works with Squeeze, works with Mac OS X, works with Windows 10.

Works initially on Jessie with KDE desktop, but I get a weird errors in the Xorg.log and then the sound quality (which starts perfect) starts to degrade (seemingly with events in the UI), and quite quickly degrades to unlistenable. The exact behaviour clearly depends on activity of some sort, but 4 or 5 minutes is not uncommon.

I've tried the xf86-input-evdev from unstable, I've tried building it from source (2.10.1), the weird errors remain.

The errors look like this bug, and I commented to that effect.

https://bugs.freedesktop.org/show_bug.cgi?id=89473#c9

I tried some vague attempts to make Jessie sound work more like Squeeze, on the assumption it was changes to have priority but that makes no difference.

The author however thinks it is unlikely to be responsible for the sound quality issue.

Anyone got any idea where to go next?
